This ship is close to my Fleet Tor'Kaht, which I have equipped with 3x DBB and an Omega torp, since DBB have a wider arc that gives me more final DPS than small arc of DHCs. I dont know if this is possible with 5 forward slots... it will be hard to keep 4x DBBs fully powered and operational.
A lot of people thought the Scimitards would all be DHCs, and most of them seem to be running beam arrays because of the turn-rate.
PVE it doesnt matter. PVP, I would be thinking about the rear blind spot. Turrets and beams arent going to keep people away back there, so probably need something like mines. If you close off the rear enough you could maybe get away with DBBs on the front. Its a cloak not a battlecloak.
